Radiant Rig Help

Radiant Rig is my implementation of the paper “Raycast based auto-rigging method for Humanoid meshes” by Romain Lopez (ESGI Paris) and Christophe Poirel (ESGI Paris). It works only in Blender 2.6.8 and above. Radiant Rig depends upon Rigify. Radiant Rig automatically creates a human meta-rig sized to fit the selected figure. Download Radiant Rig here.


Rigify comes pre-installed in Blender. It needs to be activated in order for it to work with Radiant Rig.

1) Go into User Preferences (Windows CTRL+ALT+U or Macintosh CMD+,)


2) Click on “Addons” and search for “Rigging: Rigify”. Make certain there is a checkmark beside Rigify.


3) Click on “Install from file” and select the downloaded Radiant Rig Zip file.


4) Click on the box beside “Rigging: Radiant Rig” to active Radiant Rig.


5) Click on “Save User Settings”.



1) Click on ‘N’ to show the Properties Panel. Load your figure into Blender.


2) Click “Generate Auto-Rig”.


3) You might get the following message:

Calculation Error. Unable to find all limbs.
Possible Causes:
* Limbs are covering each other.
* Not a humanoid figure.
* Clothing mesh on top of figure: Try with split mesh.


4) Click on “Split Mesh”


5) When the splitting is complete, click on “Generate Auto-Rig”.



6) Once rig calculation is complete, a new rig based on the Human Meta-Rig will be generated.



6) Click on “Bing Rig” to bind both the clothing and the main figure to the rig.


7) Your rig is now attached to your figure.

Rather than type out text tutorials, I thought I would collect links to some of the best video tutorials for Blender. Most of the tutorials give tips for rendering but the last tutorial shows how to use GoB, an unofficial GoZ for sending models between Blender and ZBrush.

LuxRender tutorials

  2. Introduction to Lighting in Luxrender and Blender (9:07 minutes)
    Is your LuxRender a black screen? You may have the lights turned the wrong way. Avoid this with the help of Frederik Steinmetz

  3. The Secrets of Realistic Texturing in Blender (34:27)

Blender with BSurfaces: My Dream 3D app come true?

BSurfaces v1.5 on Vimeo

Image taken from a video by Blend_ideas at vimeo.

Three years ago, I knew about Blender but it still had many usability issues and had poor implementations of the things I was used to in commercial software.

The move to the new 2.5 interface made Blender more attractive and easier to learn. With the addition of BSurfaces and Cycles, Blender is seriously giving commercial software a run for its money in the areas of modeling and rendering respectively. External renderers like YafaRay and LuxRender make Blender even more competitive. Sculpting and animation are two areas where Blender is still not as strong as compared to commercial software like ZBrush (can’t rebuild subdivision levels, can’t handle billion+ polygon counts, and a limited number of sculpting tools) or Maya (more compatibility with other 3D apps and sophisticated rigging and animation tools) but given the rate of improvement this could change.

What is so great about BSurfaces? Put simply, BSurfaces allows an artist to create an intricate surface with just a few hand drawn lines; ZBrush has a similar feature but Blender’s version preserves good topology. BSurfaces also supports retopology in a method very similar to Topogun. Draw the guidelines and BSurfaces fills in the polygons. Although it does not come standard with Blender, you can download the addon from Blender Artists Bsurfaces thread (Dec. 1, 2015). If Blender had been this good in 2009, I could have saved myself some serious change. Click on the image above to see BSurfaces in action in a video by Blend_Ideas.

Update August 17, 2012: QRemesher in ZBrush 4R4 provides similar topology functions to Blender’s BSurfaces.
